I have pain & discomfort in my lower abdomen, on the right side. It started about 2 days ago and is getting progressively worse, but is still a moderate pain. Hurts when I move, walk, stand, lay down. Not as bad when I m just sitting, then it s more of a dull ache. No vomiting or diarrhea, but have more gas than usual. Do you think it could be appendicitis?
